Coral Tree Nursery® 

Innovative Growth and Outplanting

Corals can grow and reproduce both sexually, through spawning, and asexually, through fragmentation: if a branch falls off on the reef and conditions are favorable, it can reattach and begin to grow a new colony.

By collecting small branches or fragments from a colony and raising them in offshore nurseries, we can take advantage of this naturally occurring process also known as propagation.

Coral Tree Nursery®

In 2010, we developed the Coral Tree Nursery®: a simple framework of PVC pipe that resembles the shape of a tree. The nursery tree is tethered to the ocean floor and buoyed with a subsurface float. Coral fragments are hung from the branches of the tree using monofilament line.

The tree floats in the water column and is able to move with storm-generated wave surges. This dissipates wave energy preventing damage to the tree structure or the corals themselves,

“Reef-Ready”

Corals are grown in the nursery for approximately six to nine months. After they have reached a substantial size, they are tagged and taken to a carefully selected reef restoration site where they are attached directly to the reef using a non-toxic marine epoxy.

Tens of thousands of corals are produced through our pioneering propagation techniques and housed in multiple offshore coral tree nurseries. We currently have 7 offshore coral nurseries in South Florida from Carysfort Reef to Key West.
